Ann: Presentation at PDAC Converntion, Toronto, page-3

Just FYI Ironman.

This is from Ioneers page in the overview section:

There is also strong potential to produce lithium hydroxide at the mine site. Metallurgical testwork to determine the best rourte to producing lithium hydroxide at Rhyolite Ridge will be undertaken as part of the Definitive Feasibility Study.

So we may find out more information on this in Q3 of this year. 

I also saw a few people discussing on ASX:ORE the purification circuit of Lithium to Lithium Hydroxide. While battery grade lithium hydroxide might bring in more money it will cost more to do this process. Similarly technical grade will cost less to produce but also sell for less. I think part of what they do will be shaped by what sort of deal they can get for finance initially. This is just my opinion of course.
